Title: Heat recoverable alloys
IPC: C22F1/00
Filed: 1971-06-17
Abstract: 1338278 Nickel-base alloy; preparation RAYCHEMCORP 17 June 1971 [2 July 1970] 28456/71 Heading C7A and C7D A nickel base alloy contains, in atomic percent, 49.1 to 50.2% titanium and 2.1 to 4.7% iron, the balance being nickel and impurities. Preferably the iron is present at between 3.2 and 3.6 atomic percent. Impurities present should not exceed 0.1 per cent by weight of carbon, 0.2% of nitrogen and 0.2% oxygen, other metal or non-metal impurities may also be present, the total impurity level not exceeding 0. 5 per cent by weight. The alloy is particularly suitable for use as a coupling for hydraulic circuits in aircraft, the martensitic transition temperature being well below the operating temperature required. The alloys have the property of being heat-recoverable i. e. they may be deformed at below the transition temperature, but revert to an undeformed condition when heated again to above that temperature. Alloy Preparation Strips of each of the constituent metals are assembled in bundles, each strip having the same length and width and the numbers being such as to give the required proportions at any crosssection. The bundles are then melted in an inert atmosphere progressively along their length, the falling droplets being collected in a cold copper mould. The resulting ingot was then subjected to a further heating step in an inert atmosphere, a molten zone passing along the ingot at 0.5 cms/ minute to produce a void-free bar.

Title: Improvements in or relating to the manufacture of glucose from potatoes
IPC: C13K1/06
Filed: 1939-10-23
Abstract: 536,020. Glucose. CORN PRODUCTS CO., Ltd., and WASCHER, H. G. Oct. 23, 1939, No. 28507. [Class 127.] In preparing glucose from potatoes, the conversion of the starch is carried out in the presence of the fine fibre of the pulp. The potatoes, washed and scrubbed, are pulped, and passed over a sieve to remove unground portions and the large portions of the pulp. The resulting material is diluted with water and centrifuged to remove soluble substances, and is sieved to remove coarse fibre. The mixture of starch and fine fibre is treated to convert the starch to glucose, and the solution is filtered to separate the fine fibre which has become partially hydrolised and is suitable for use as a cattle food.

Title: Improvements in methods for the production of resilient rollers
IPC: B65G39/00
Filed: 1953-10-19
Abstract: In making resilient rollers especially for printing, metal spindles are covered with polyurethane synthetic resins produced by the reaction of cross-linkable polyesters with diisocyanates; small amounts of plasticiser may be added to the mixture.  The mixture may be introduced into a mould containing a metal (e.g. steel) spindle by pouring, centrifuging (to a layer of 8 millimetres to 30 millimetres thickness) or injection under pressure and then allowed to react at room temperature or with slight heating.  The method may be modified by centrifuging a surface layer and then filling the space between the surface layer and the spindle with the same material which may be softer than the surface layer.  In an example, 100 parts by weight of polypropylene adipate were mixed by stirring at 110 DEG C. successively with 20 parts of dioctyl phthalate and 17 parts of naphthylene-1,5-di-isocyanate; after 10 minutes 2 parts of butylene-1,4-glycol were added to the mixture which was then poured into the moulds and kept for three hours at a temperature of 110 DEG to 120 DEG C.ALSO:Resilient rollers especially for printing have a surface made from polyurethane synthetic resins produced by the reaction of cross-linkable polyesters with di-isocyanates; varying amounts of plastizer may be added to the mixture to adjust the softness.

Abstract: 174,995. Mond, A. L., (International Precipitation Co., Inc.). Oct. 15, 1920. Gases, electrically precipitating suspended particles from.-Deposits are removed from discharge or collecting electrodes, without cutting off the electric current, by scrapers or by motion of the electrodes over rollers. Scrapers may consist of pads of felt which may be moistened, of sheets, cones, or tubes, of current-supply contacts, or of the edges of orifices through which the moving electrodes enter and leave the precipitation chamber. In one construction, an endless wire or ribbon a, Fig. 1, forming the discharge electrode passes between collecting electrodes d, e and over rotating, continuously or intermittently, or reciprocating rollers b, c. Scrapers may be situated either within the electric field or outside the field as at f, g. A scraper may be carried a certain distance by a movable electrode and then moved back by hand or automatically. Fig. 2 represents an endless wire electrode 1 passing through tubular collecting electrodes 6 and over pulleys 2, 3, situated outside the precipitating chambers and optionally within special chambers 4, 5 supplied with pure air which may be under pressure and at a controlled temperature. The upper pulley 2 is resiliently mounted, for instance by means of a lever 11 and weight 13. The pulleys or parts thereof are of insulating material. A scraper 15 acts preferably on the ascending or taut side of the wire. Contacts 14, 18 bear on the wire in the pulleys. Current may also be conveyed through the pulleys. Low-pressure heating current may be passed through the wire by a battery 17, insulated for high pressure. In other forms, continuous, reciprocating, or intermittent motion of the collecting electrodes may be provided for by constructing them as series of hinged or separate strips attached to endless chains. Two endless vertical wires, or a single wire passing vertical wires, or a single, wire passing repeatedly through the precipitating space in a horizontal direction, may form the discharge electrode. In other modifications, the electrodes are stationary and the scrapers movable by hand or automatically. Scrapers for both electrodes may be mechanically connected, and may be wholly or partly of insulating-material.

The dividers produce a hyperbolic variation of clock frequency. Preferably the counter counts up from zero until full at the clock rate and then down with the hyperbolic varying clock rate. As shown, a start signal at the beginning of the period enables gate CG to pass clock signals from source MO via fixed divider SD to counter U/D.C. When the counter is full CG operats to enably the variable dividers RM1, RM2 and to pass the clock pulses directly thereto. The p output pulses from RM2 pass via SD to the counter which now counts down and the division factor is continually varied in accordance with the counter readings. At the stop signal, CG removes the enabling signal from the dividers and the counter reading is displayed on device DD.  The variable dividers comprise a series of bistable devices forming a counter and a plurality of gats enabled by the binary, parallel counter output. The fixed divider SD removes gitter introduced by the variable dividers. The circuits may also be used to measure frequency.
